HATCH-ROLLER.

SPECIFICATION forming part of Letters Patent No. 436,046, datedSeptember 9, 1890.

Application filed July 8, 1890. Serial No. 357,649. (No model.)

To all whom it may concern.-

Be it known that I, STEPHEN F. PALMER, J r., a citizen of the UnitedStates of America, and aresident of Ogdensburg, in the county of St.Lawrence and State of New York, have invented certain new and usefulImprovements in Hatch-Roll rs for Unloading Lumber from Vessels; and Ido hereby declare that thefollowing is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, in which- Figure 1 is a perspective viewof my improved hatch-roller, and Fig. 2 is a transverse sectional Viewat the divisional point marked A in Fig. 1.

Like letters of reference indicate corresponding parts throughout bothfigures.

The usual method of unloading lumber from a vessels hold is to rest theside of the plank to be unloaded against the upper edge of thehatcli-combin g, and while the plank is resting thereupon force itupward and outward until sufficiently above deck to be grasped andlifted bodily therefrom. \Vhen unloaded in this manner, the rubbing ofthe plank against the upper edge of the hatch-combing greatly adds tothe labor of unloading, and also has a tendency to mar the plank andtear the hatchcombing.

The object of my invention is to obviate this additional labor and riskof damage by providing a roller mounted upon a portable frame-work andadapted to rest over and fasten upon the hatch-combing as ordinarilyconstructed in vessels, and. by means of which the said rubbing andfriction of the plank against the hatch-combing is overcome.

Referring to the accompanying drawings, B represents the rollerjournaled in the bearings C O at either end and provided with aratchet-Wheel D near one end, the teeth of which engage with the ratchetE, movably attached to the frame-work, as shown. The

legs F F of the'frame-work are intended to rest over the outer edge ofthe hatch-combin g, while the legs G G rest over the inner edge thereofand are secured thereto by means of the set-screws H H in Fig. 2.

M represents a section of the hatch-combin g with my improvedhatch-roller in position thereon. The cross-bars I I may be integralwith the frame-Work or fastened thereto by rivets or screws, as shown.The bearings O C, I make preferably detachable, as shown, so that whenthey are detached from the frame the roller may be readily removed; butit is obvious that they may be drilled into the framework and the rollerremoved by separating the frame-work at the cross-bars, as shown.

My entire improved hatch-roller I make preferably of wrought-iron; butit may be made of any suitable known material.

In operating my improved hatch-roller I first attach it to the combingof the hatchin the position shown at Fig. 2 by turning the set-screws HH. I then rest the side of the plank to be unloaded against the innerside of the roller B, the lower end of the plank being in the hold ofthe vessel. I then force the plank upward and outward from the hold ofthe vessel, while still resting against said roller, until the plank issufficiently expelled from the hold of the vessel to be grasped andlifted bodily from the roller. The pawl E, engaging with theratchet-wheel D, prevents the roller from turning backward and returningthe plank resting thereon to the hold when the workman releases thestrainupon the plank in order to get a fresh grasp thereof.

Having now described my improved hatchroller and method of using thesame, what I claim as. my invention, and desire to secure by LettersPatent of the United States, is

1. A hatch-roller journaled into a framework provided with legs adaptedto straddle the hatch-combing and fastened thereto, substantially asshown and described. I

2. A hatch-roller journaled into a framework provided with legs adaptedto straddle the hatch-combing and fastened thereto, in combination withthe ratchet-wheel and rat chet, substantially as shown and described.

In testimony that I claim the foregoing as my own I have hereuntoatlixed my signature in presence of two witnesses.
